## What is Suila?

Suila is a completely free video editor for iPhone and iPad.

No accounts, no ads, no tracking, no personal data collected. Suila doesn't upload your videos, audio, or projects anywhere on its own — everything stays on your device.

Its signature is multi-point speed curves — bend time with a single curve for slow motion and dynamic speed changes. Cut, caption, and score your video in minutes.

Why you'll love it:
• Multi-point speed curves (signature): add control points for smooth, dynamic speed changes and slow motion.
• An intuitive timeline: split, trim both ways, long-press a clip to drag it into a new order; deleting closes the gap automatically — no black frames left behind.
• Auto captions (on-device): turn speech into captions in dozens of languages, depending on your device — Traditional Chinese, English, Japanese, Korean, Spanish, German, and more. Generate from the main video or a picture-in-picture clip; adjust length and density; edit, split, and merge by hand — and drag them anywhere on the preview.
• Auto face mosaic: detect and track faces frame by frame to mosaic or blur them; tap to keep your star unmasked, even in a crowd.
• Fonts, your way: 5 built-in commercial-use CJK typefaces (including the handwritten ChenYuluoyan), or import any .ttf/.otf of your own.
• Filters & color: cinematic LUTs plus brightness, contrast, saturation, temperature, and tint — plus one-tap underwater correction that brings back the red the water swallows.
• Text & stickers: free positioning, fonts, colors, letter & line spacing, in/out animations, and emoji.
• Transitions & keyframes: 19 transitions — dissolve, fade, push, slide, and zoom, plus whip pan, glitch, swirl, and more; animate position, scale, and opacity.
• Picture-in-Picture: layer a second video — or a photo — over your main clip, with its own audio; captions generated from it move along with it.
• Audio from video: extract any clip's soundtrack as an editable track; add music and royalty-free sound effects.
• Watermark: put your name or brand — text or a logo image — on your video; position, size, and opacity are yours, shown the whole way through.
• Canvas & end card: 9:16 / 1:1 / 16:9, plus an optional "Made with Suila" end card (free, toggle off anytime).
• 4K export: preview is export — what you see is what you get.

Cut it. Nail it.

本当に使いやすく、無駄な機能がない、まさに神アプリ。
操作も非常に直感的で、また字幕機能もとても便利。あとは字幕を自動で任意の言語に翻訳してくれる機能をつけてくれると本当に助かる。お願いします。

**Developer response:** 温かいレビュー、本当にありがとうございます！一人で作っているので、大きな励みになります。字幕の自動翻訳は、翻訳字幕・二言語字幕の形で実現できないか検討中です。楽しみにお待ちください！

## Version history (last 5 releases)

### 1.7.1 — 2026-08-21

This update brings export stability and live color preview — plus official sticker packs you can download right in the app!

• Export fix: projects with face mosaics (especially many clips with speed changes) could fail to export — fixed, with far lower memory use.
• Live color preview: the picture updates as you drag the filter and adjustment sliders — no more letting go to see the change.
• Official Sticker Packs: tap + in the sticker panel to browse and download official packs; installed ones show "Added", and "Update" when a new version is out.
• Caption model download: generating captions for the first time now shows real download progress instead of sitting at 0%.
• Truer waveforms: audio waveforms now follow the actual loudness, so beat-matching is easier.
• Other bug fixes and stability improvements.

### 1.7.0 — 2026-08-18

The big sticker update — plus Freeze, by popular request!

• Your stickers, made by you: turn images or GIFs into sticker packs in the Sticker Workshop on our website, then scan a QR code, AirDrop or tap a link to add them to Suila — and share them with friends.
• Animated stickers: stickers that move! They play right in the panel — tap one to drop it into your video.
• Sticker search: however many you collect, find any sticker by name or keyword.
• Freeze: hold the video on exactly the frame you want (a wishlist feature).
• A whole new timeline: every clip now shows its real consecutive frames, so you can see where to cut at a glance.
• Smoother dragging: stickers and text show a translucent preview while you move them, so you see where they'll land first.
• Start a project with a square video and the canvas is square too — no more black bars.
• Recording fixes: a duration occasionally recorded too long and a counter that ran fast during recording are both fixed.
• Effect fix: some effects occasionally showed no effect on newer iPhones.
• Other bug fixes and stability improvements.

### 1.6.1 — 2026-08-07

• Auto captions can pick their source: caption the recording or the picture-in-picture — your choice. A recording is the cleanest speech, so the captions come out best.
• A 15th effect, Halftone: colour print screens whose dots grow finer as you lower the strength, for an offset-print look.
• Fixed a recording that occasionally ran to the end without landing on the timeline.
• When the system hiccups mid-export, the export now retries itself once — most of the time you'll never know, beyond it taking a little longer.
• A save to your photo library interrupted by the system retries automatically; if it still fails, the finished video is kept so "Save Again" costs seconds instead of re-exporting.
• Clearer export failures: running out of space, running out of memory and an overheating device each say what happened and what to do.
• Deleting a clip no longer asks first — it's always undoable. Deleting a project now does ask, because it takes the imported media with it and cannot be undone.
• Other improvements: fonts are listed by their full names, the caption panel's messages are no longer hidden behind the panel, and the project list no longer flickers when you swipe to delete.

### 1.6.0 — 2026-08-04

• New "Effects": the toolbar's Animation button is now Effects — 14 looping styles in four categories, Mood, Retro, Motion, and Texture (Vignette, Light Leak, Dreamy, Film Grain, VHS, Old Film, Shake, Pulse, Strobe, Glitch, Speed Lines, Pixelate, Chromatic, Scanlines), each with strength and speed. Every thumbnail previews on your own frame, so you see it before you pick it; the old fade in/out moved into the panel's "In & Out" tab.
• New "Voiceover": tap Voiceover in the toolbar and, after a 3-second countdown, record narration while the preview plays. Takes land on their own track — trim, volume, and fades work like any audio clip.
• Built-in teleprompter: paste your script and it shows over the top of the preview while you record, with three text sizes and manual scrolling. Botched a take? Tap "Delete Last Segment" — the playhead jumps back to the start of the take so you can retry right away.
• New "Mute track": every lane now has a speaker button at its head. One tap silences the whole track (exports match), and clip volume settings are kept.
• Duplicate a project: long-press a project in the library to make a copy — a safety net before big edits. Your footage isn't duplicated, so the copy takes almost no space.
• Auto-caption line breaks, rebuilt: lines break only at word boundaries and follow punctuation, numbers stay with their units, and connectives like "so" and "then" lead the next line instead of dangling at the end of the last one. Long sentences read far better, especially in Chinese.
• Caption "Polish" no longer just disappears: when it's off or the model is still downloading, the panel says why and where to turn it on.
• Smarter storage for caption language models: languages you haven't installed or used are given up first, so the ones you rely on aren't dropped.
• Fixed: the cover no longer goes missing after undoing a cover change; adding music no longer stacks on top of existing music — it snaps in right after it.
• Polished: a clearer import icon, empty-project hints no longer run to the screen edge, and export failure messages say more about what went wrong.

### 1.5.4 — 2026-07-24

• New "Cover": tap the Cover card at the start of the timeline and pick a video frame (filters and captions included) or a photo from your library as the video's cover — platforms that grab the first frame for the thumbnail will use it.
• Fixed an export that could hang indefinitely on iOS 27.
• When a clip lives in iCloud and you're offline, Suila now says so and shows download progress instead of a blank preview.
• Fixed text, stickers, and picture-in-picture disappearing when media was missing.
• The export frame is easier to see: content outside the canvas is marked with a border and dimming.
• On older devices that can't run auto-captions, Suila now says it isn't supported on this device instead of a misleading error.
